In flowers called columbines, evolution of the length of nectar spurs–the long tubes leading to plants’ nectar–happens in a way that allows flowers to match the tongue lengths of the pollinators that drink their nectar, biologists have found.

The pollinators of Columbines, are “bumblebees, hummingbirds and hawkmoths”. This calls for another Columbine photo I think.
